Things You'll Need
Door handle tool
When installing some locksets, you have to make sure that the lockset is "handed" for your door. This means that, after you install it, the key hole will be on the outside, and the lever handles will extend toward the center of the door. If you buy the wrong lockset, you won't be able to install it correctly on your door. Schlage gets around this problem by making its door handles reversible. You can reverse a Schlage door handle to fit your door, regardless of which side it's handed on.

Insert the key into the lockset. Turn the key 90 degrees counterclockwise, until it is vertical in the key hole.
Look for a small hole in the side of the handle, near the face of the lockset. Insert the end of a door handle tool or small flat-head screwdriver into the hole. Press in on the tool or screwdriver while pulling out on the handle. Slide the handle off the lockset until it butts up against the key.
Turn the key 90 degrees clockwise, and pull it out of the key hole. Pull the handle the rest of the way off the lockset.
Press the tool or screwdriver into the hole on the other handle. You don't need to insert the key or turn the lock button. Pull the handle off the lockset.
Slide the handle from the side with the key hole over the lockset shaft. Press in on the handle until it locks in place.
Slide the handle from the lock-button side of the lockset onto the shaft until it butts against the retaining clip. Insert the key in the key hole, and turn it 90 degrees counterclockwise. Press in on the handle until it locks in place. Remove the key.
Many models of Schlage locksets have interchangeable handles. You can remove handles to reverse them, or to install new handles for an updated look.
Pull out on the handle on the key-hole side after you remove the key to make sure it is firmly locked in place. If the door handle comes off, an intruder can easily bypass the lockset.
